On June 3, Hangzhou Every Step Materials Technology Co., Ltd. was granted another invention patent by the State Intellectual Property Office. The patent name is: A rapid repair construction method for underwater pipeline leakage, patent number: ZL 2020 1 0531288.0.
Rapid repair of underwater pipeline leakage has always been one of the challenges in the engineering industry. Leakage of underwater pipelines not only causes resource waste but may also cause environmental pollution. Taking the caisson pipes of offshore oil platforms as an example, caisson pipes can be corroded by seawater and leak, thus polluting the marine environment. When the leakage is above water, ordinary repair methods can be used, but there is still a lack of effective repair methods for underwater pipelines. Generally, only temporary methods are used, such as wrapping and covering, which can only slow down the leakage but cannot effectively solve the problem. Therefore, a rapid underwater leakage repair technology is needed to solve the leakage problem of underwater pipelines and address safety hazards caused by thinning pipe walls.
In response to the above problems, this invention provides a rapid repair construction method for underwater pipeline leakage. By installing a U-shaped steel casing in the planned pouring area of the leaking pipeline and pouring a fast-setting polymer resin concrete that does not segregate underwater, rapid repair of underwater pipeline leakage is achieved. The underwater leakage repair technology provided by this invention, through field tests, can fully utilize the good bonding performance between the polymer resin concrete and metal materials and the high curing strength, greatly improving the repair effect.
Test site picture
This underwater leakage repair technology has been successfully applied in a water diversion project in Zhoushan City, Zhejiang Province. The company's on-site technical personnel and the construction site manager cooperated well, successfully completing the underwater repair construction using this technology and achieving the expected results.
Construction site picture
The company will continue to make full use of its existing technology and equipment conditions, through equipment introduction, training of relevant technical personnel, and combining with engineering practice applications, to further improve the underwater pipeline leakage repair technology and promote the development of underwater leakage repair technology to a new level.
